Abstract

[Problem] To provide a molding sand regeneration method and regenerating system that effectively separate magnetically adhering material from the molding sand. [Solution] Provided is a molding sand regeneration method characterized by: removing metal powder and metal fragments by magnetic separation with a first magnetic flux density and removing magnetically adhering material by magnetic separation with a second flux density higher than the first flux density from molding sand S that has been separated from a casting by a shot blast; and removing, from the molding sand, material that includes carbides adhering to the surface of the molding sand by dry mechanical regeneration.
